New York City Building Energy and Water Benchmarking Data

Local Law 84 mandates annual energy and water benchmarking for New York City buildings over 50,000 square feet. The dataset contains reported data from 2022 onward, submitted via the EPA's Portfolio Manager tool. It includes property IDs and associated tax lot (BBL) or building (BIN) identifiers.

Use Cases

• Analyze energy consumption trends across building types using reported electricity, natural gas, and steam data.
• Correlate water usage with building size and fuel oil consumption to identify conservation opportunities.
• Assess greenhouse gas (GHG) emissions for compliance with Local Law 97 based on reported fuel and energy metrics.
• Map building energy performance by geographic area using Borough, Block, Lot (BBL) identifiers.

Strengths

• Data is mandated by Local Law 84, ensuring consistent reporting from a defined population of large buildings.
• Includes multiple energy and water metrics such as electricity, natural gas, steam, and fuel oil for cross-utility analysis.
• Covers a major metropolitan area (New York City) with data from 2022 to the present.

Limitations

• Sample size and row count are unknown, limiting assessment of statistical power and coverage.
• Data quality depends on owner-submitted reports via the EPA Portfolio Manager, which may contain errors or omissions.
• Limited to buildings larger than 50,000 square feet, excluding the vast majority of the city's building stock.
